QARBULQETEFRU Patented. July 33., 19MB.

Application filed October 18. 1905. serial No. 283,24 i= This invention relatesto an apparatus for.

I enriching gases used for illuminating and cheap, simple,

heating purposes by the addition thereto of hydrocarbons, said apparatus being equally well ada ted for carbureting air.

dhe o ject of the invention is to provide a and efficient device whereby gases for. illuminating and heating purposes may be enriched, and thus better subsequent combustion of said illuminating-gases secured, raising the candle-power thereof and increasing the heat units contained in coal and water ases, thus resulting in the production of power with less cost.

The object of the invention is again to carburet air in suburbs oi cities not provided with gasmains.

T he invention consists in the combination and arrangement, of parts set forth in the following specification and particularly pointed out in the claims thereof.

Referring to the drawings, Figure l is a vertical central longitudinal section, partly in elevation, illustratin the as mixing and atomining device with t .e tan 1 for storage bi" the hydrocarbon oil in connection therewith. Fig. 2 is a section, partly in elevation,-taken on line 2 2 of Fig. 1 looking downwardly in said View. Fig. 3 is a section, part1 in elevation, taken on line 3 3 of Fig. l. ig. 4.- is an enlar ed detail lan of one of the apertures lea in from tiie expansion to the separating cham or with a portion of the casing shown in section. Fig. 5 is a detail section taken on line 5 5 of Fig. 4.

Like numerals refer to like parts throughout the several views of the drawin s.

In the "drawings, 8 is a casing ibrmed of sheet metal suitably fastened together and comprising in its construction a horizontal artition 9, which. extends laterally across the interior of said casing, dividing said in terior into an upper compartment 10 and a etter light and greater heat or.

localities where gas 1S not -pro- Y, curable, as in email country towns or entire lower compartment 11. The lower com partment 11 is divided by cylindrical artitions 12and 13 into her 142, an intermediate chamber 15 sur rounding said inlet-chamber, and an expa sion-chamber 16, which surrounds said intermediate chamber, the outer wall of said expension-chamber being the outer wall 23 oil the casing 8. The intermediate chamber 15 is subdivided. into a lurality of com artments 17 by radial walls 18, extending iv the artition 12 to the partition 13 and from the orizontal partition 9 to the bottom 19 of the casing 8.

The partition 20 of the casin tothe bottom 19 thereof, and thus divides t e upper. compartment '10 into a cylindrical outlet-chamber 21, rounded by a separating ber 22, the inner wall of said separating chamber being formed by the partition'i2 and the outer wall thereof by the outer wall 23 of the casing 8. The separatin -chamber 22vis subdivided into a plurality o compartments 2% by radial partitions 25, which extend from; the wall 12 to the wall 23 and iroin the top 2() to the horizontal partition 9.

Communication from the inlet-chamber 14; to the compartments 1'? of the expansionchamber 16 is established by means of apertures 26, extending through the partition 12 and from the compartments 1'? to the expansion-chamber 16 by apertures 27, extending through the partition 13.

Communication is established from the expansion-chamber- 16 to the radial compartments 2a in the separating-chamber 22 by apertures 28, which extend through the .orizontal partition 91. Communication between the radial compartments 24 and the outlet-chamber 21 is established by means of apertures 29, extending through the artition 12.

Gas or-air is a mitted to the inlet-chamber 14 through'the pipe 30, the supply of gas or air passing through said pipe being controlled by a suitable valve 31. After the gas or air has been treated and enriched, as hereinafter described, it passes out from: the outlet-chamber2l through the outletipe 32;, said outlet-pipe being also provide with a valve 33 to control the passage of the en riched gases or air therethrough. A by-pass 34 connects the inlet-pipe 30 with the outleta cylindrical inlet-c am 12 is extended from the top.

which is sur or stripping chain pipe 32 and is provided with a valve 35 to control the amount of gas or air admitted to the outlet-pipe 32 directly from the inlet-pipe '30 without passing through the different compartments of the casing 8.

In order to strengthen the casing and to afford a support for the horizontalpartition 9, the inlet-pipe is extended downwardly in the interior of the inlet-chamber 14 to the bottom 19 of the casin and is closed at its lower end, but is provi ed with apertures 36' near the top of the inlet-chamber 14, through which the gas or air enters said chamber from the inlet-pipe 30. Hydrocarbon oil is supplied to the ex ansion-Chamber 16 by means of a pipe 37, W ch is supplied with a suitable connection 38 and with valves 39 40 to regulate the flow of the hydrocarbon oil, such as gasolene, to the expansion-chamber 16 from the supply-tank 41. The oil thus supplied to the expansion-chamber 16 passes through apertures 53 in the-bottom of the partition 13 and also in the bottom of the radial walls 18 whereby said oil may circulate from said expansionchamber to 'and throughout the radial compartments 17. Said sup ly-tank is a formed of suitable sheet materia and'filled b any suitable means, 0 the inletvalve 43 an is preferably by means ipe 42, which is supplied with a tunnel 44. The supply-tank 41 preferably connected from the top thereof means of a pipe 45 to the separatingamber 22, said pipe 45 being provlded with a suitable connection 46 and with'valves 47 and 48.

Each of the radial compartments 17 is filled with a combination of absorbent and draining material 49, said material consisting, preferably, of Manila rope cut in len the to form wicks 50, which extend from the ottom 19 of the casing to the top of said intermediate chamber and'in contact with the partition 9. Said Manila rope is wrapped with twisted crash and asbestos, and the spaces between the wicks 50 are filled with excelsior 51. The radial compartments 24 of the se arating or strip ing chamber 22 are also filled with wicks 52, formed of absorbent material; but in these upper compartments said wicks 52, of absorbent material, are formed, preferably, of Manila rope, the twist ed crash and asbestos being omitted, but the spaces between the celsior 51.

It will be understood that the different radial compartments 17 and 24 are completely filled with the wicks of absorbent material hereinbefore described; but in the drawings only two of said compartments 17 and two of the compartments 24 are illustrated as filled with absorbent material. The apertures 26, 27, 28, and 29 are covered with wire-gauze to prevent any extraneous material being accidentally carried into the different chambers by the gases or air.

rope being filled with ex from the expansion-tank 41 through the pipe 37 into the expansion-chamber 16 and stands at about the same level in said expansionchamber as it does in the supply-tank 41. The wicks 50 "by capillary attraction feed the oil upwardlyto the top of the radial compartment 17 directly beneath the partition 9. Gas or air is introduced into the inlet-chamber 14 by means of the inlet-pipe 30 passing from said inlet-pipe into said inletthe apertures 36. From the inlet-chamber 14 said gas or air passes through the apergtures 26, said a ertures bein small and of uniform size an one aperture being supplied for each of the radial compartments 17. The gas spreads through the absorbent material, whic is saturated, as hereinbefore described, with the hydrocarbon oil, until it reaches the outer wall of the intermediate or enriching chamber 15, from which it passes through apertures 27 of uniform size into the expansion-chamber 16. The gas then passes upwardly through apertures 28 of-uniform size in the partition 9 into the radial com artments 24. of the separating or stripping 0 amber 22. Said gas then asses through the ab.- sorbent material in sai radial com artments 24 and through the apertures 29, a so of uniform size, into the outlet-chamber 21, and thence through the pipe 32 to any desired gas-burners.

It will be noted that the enriching or intermediate chamber 15 is completely surrounded and protected from outside'changes in temperature by the ex ansion-chamber, which. entirely surrounds t e same, and b the se arating or stripping chamber, w'hic extend; over the entire top of the same. As the gas passes from the inlet-chamber 14 to the exp ansion-chamber 16 it is very much enriched, takin on particles of the hydrocarbon oil contained in the absorbent material,

this enriching or carbureting taking place at jected to combustion and where the atoms are subjected to the heat of the as-flame, which is normally about 2,000". is the gas passes from the expansion-chamber and into the converging compartments of the strippin or separating chamber 22 the velocity of sai gas will be increased, thus aiding atomization by friction, the gas finally delivered from each convergin avenue or COIIIPfiIlh ment to the cylindrica outlet-chamber 21 being of the lightest quality.

The advantages of my improved device .for mixing and atomizing gases is that the chamber through izing degree, all

gases are not only enriched, as hereinbefore set forth, thus rendering in the case of illuminating-gas gases of higher candle-power and in the case of coal, water, and natural gases gases of greater heating or working power, but heavy hydrocarbons may be used instead of light hydrocarbons, thus eatly reducing the risk in the use of .said If drocarbons. The heavy hydrocarbons eing used by means of my improved mixer and atomizer at a tem anger resulting from extreme pressure is eliminated, and also the condensation of said gases in the surface ipes of a house is eliminated, as he gas eaves the machine at a lower temperature than it is likely to' encounter in any building heated to a degree suitable for occupancy.

While I have described what I consider to be the preferable material and construction of the wicks for feeding the hydrocarbon oil, I do not wish to be understood as confining myself to any material in the formation of said wicks.
